DLMS COSEM Protocol Library

Kalkitech provides an easy upgrade path for Meter OEMs to implement DLMS/ COSEM protocol in their existing/ new meters by providing a DLMS Server Source Code/ Object Library (ANSI C). The stack has been written keeping in mind the hardware resource constraints typically found in metering hardware platforms and provides flexibility to trade-off between ROM and RAM storage for several large-footprint items (like configuration information, object OBIS lists).

The ROM size for a full stack, using all features is found to be about 40KB (without meter configuration information) and runs under 2.8KB RAM. Configuration info for a typical meter with about 150 objects, a few Associations and profile capture-object lists was seen to occupy an additional 15KB ROM. DLMS COSEM Source Code Library now supports DLMS COSEM TCP/IP UDP Profile also.

Key advantages of Kalkitech DLMS COSEM stack include:

• ANSI C Code that can run on all ANSI C compilers and processors
• More than 50+ meter implementations
• DLMS UA Attested
• Client and Server Source Code
• Client Test Tools for validating implementation in the meter or modem
• Subsidized implementation consulting and training provided
• Flexible Licensing for Meters, AMR Software, Hand-Held readers, Modems, Data Concentrators
• Supports Indian DLMS COSEM Companion Standard
